, stîr

Any of numerous naturally occurring or synthetic fat-soluble organic compounds having as a basis 17 carbon atoms arranged in four rings and including the sterols and bile acids, adrenocortical and sex hormones, certain natural drugs such as digitalis compounds, and the precursors of certain vitamins. Also called steroid hormone.

adj. or ste·roid·al (st

-roid

l, st

Relating to or characteristic of steroids or steroid hormones.

Steroid

A natural body substance that often is given to women before delivering a very premature infant to stimulate the fetal lungs to produce surfactant, hopefully preventing RDS (or making it less severe).

Mentioned in: Barbiturate-Induced Coma, Hypersensitivity Pneumonitis, Respiratory Distress Syndrome

steroid

[stir′oid]

Etymology: Gk, stereos + eidos, form

any of a large number of hormonal substances with a similar basic chemical structure, produced mainly in the adrenal cortex and gonads. Steroids are chemically related to sterols.

steroid [ster´oid]

any of a group of lipids with a complex molecule containing carbon atoms in four interlocking rings forming a hydrogenated cyclopentophenanthrene-ring system; three of the rings contain six carbon atoms each and the fourth contains five. Steroids are important in body chemistry and include steroid hormones such as the gonadal or sex steroids, corticosteroids,glucocorticoids, and mineralocorticoids; vitamins of the D group; and the sterols, including cholesterol, the main building block of the steroid hormones in the body. The cardiac glycosides, a group of compounds derived from certain plants, are partly steroids.

gonadal steroid (sex steroid) a steroid hormone produced by a gonad, such as an androgen, estrogen, or progestationalagent.

steroid (ster´oid),

n a group name for compounds that resemble cholesterol chemically and also contain a hydrogenated cyclopentanoperhydrophenanthrene ring system. Included are cholesterol, ergosterol, bile acids, vitamin D, sex hormones, adrenocortical hormones, and cardiac glycosides.

steroid, 11-oxy,

n the C-21 corticosteroids, all of which are oxygenated at carbon 11.

steroid, 17 α-hydroxycortico- (17-OHCS),

n term used for cortisol and other 21-carbon steroids possessing a dihydroxyacetone group at carbon 17. Serum and urinary determinations give a direct measurement of adrenocortical activity.

steroid, 17-keto- (17-KS),

n steroidal compounds with a ketone (carbonyl) group at carbon 17. Derived from cortisol and adrenal and testicular androgen. Urinary neutral 17-ketosteroids represent the catabolic end products of the endocrine glands. Produced by the adrenal cortex and testes. Increased values occur in adrenogenital syndromes, adrenocortical carcinoma, bilateral hyperplasia of the adrenal cortex, and Leydig cell tumors. Normal adult values for a 24-hour urine sample are 10 to 20 mg for men and 5 to 15 mg for women.

steroid, adrenocortical (adrenal corticosteroid),

n 1. a hormone extracted from the adrenal cortex or a synthetic substance similar in chemical structure and biologic activity to such a hormone.
2. the biologically active steroid of the adrenal cortex, which include 11-dehydrocorticosterone (compound A), corticosterone (compound B), cortisone (compound E), 17 α-hydroxycorticosterone (compound F, hydroxycortisone, or cortisol), and aldosterone. The effects of the corticosteroids include increased resorption of sodium and chloride by the renal tubules and metabolic effects on protein, carbohydrate, and fat.

steroid, C-19 cortico- (anabolic protein, N hormone),

n adrenocortical hormones similar in action to the male and female sex hormones. They cause nitrogen retention and, in excessive amounts, masculinization in the female.

steroid, C-21 cortico- (glycogenic steroid, sugar hormone),

n 21-carbon adrenocortical hormones that are oxygenated at carbon 11 or at both carbon 11 and 17. They affect protein, carbohydrate, and fat metabolism; e.g., they elevate blood sugar, increase glyconeogenesis, decrease hepatic lipogenesis, mobilize depot fat, and increase protein metabolism.

steroid, glycogenic,

n See steroid, C-21 cortico-.

steroid

a complex molecule containing carbon atoms in four interlocking rings forming a hydrogenated cyclopentophenanthrene-ring system; three of the rings contain six carbon atoms each and the fourth contains five.

Steroid derivatives are important in body chemistry. Among them are the male and female sex hormones, such as testosterone and estrogen, and the hormones of the cortices of the adrenal glands, including cortisone. Vitamins of the D group are steroids involved in calcium metabolism. The cardiac glycosides, a group of compounds derived from certain plants, are partly steroids. Sterols, including cholesterol, are steroids. Cholesterol is the main building block of steroid hormones in the body; it is also converted into bile salts by the liver.

steroid I

alfaxalone.

steroid II

alfadolone.

steroid diabetes

see steroid diabetes mellitus.

steroid hormones

see androgenic steroids, corticosteroid, glucocorticoid, mineralocorticoid, anabolic steroid.

steroid

One of a group of hormonal substances produced mainly by the adrenal cortex. They fall into three main groups: glucocorticoids (or glucocorticosteroids), mineralocorticoids and sex hormones. The glucocorticoids have antiinflammatory properties reducing vasodilatation, stabilizing mast cells thus decreasing the release of histamine and maintaining the normal permeability of blood thus preventing oedema. They also inhibit the production of prostaglandins, which mediate some of the effects of inflammation. They are widely used in the treatment of a variety of inflammatory diseases of various organs including the eye (e.g. allergic and vernal conjunctivitis, corneal diseases, iritis, uveitis and sympathetic ophthalmia). The natural glucocorticoids, such as cortisone and hydrocortisone, are effective only at high doses. Synthetic and more potent steroids are used in ophthalmic treatment (when used as ophthalmic preparations they are called corticosteroids). They include, betamethasone, dexamethasone, fluorometholone, prednisolone and triamcinolone. See antiinflammatory drug.

steroid

adjective Pertaining to steroid hormones noun 1. A cholesterol-derived lipid that is the parent compound for steroid hormones of the adrenal gland and gonads 2. Steroid hormone A hormone produced from modified cholesterol Examples Hormones from testis, ovary, adrenal cortex, etc Uses Relief of swelling, inflammation. See Anabolic steroid, Corticosteroid, Glucocorticosteroid, Ketogenic steroid. Cf Peptide hormone 3. Any compound–eg, bile acids, cardiac glycosides, vitamin D precursors, that is struturally similar–ie, has a cyclopentaphenanthrene core–to steroid hormones

Patient discussion about steroid.

Q. Does steroids make children shorter? My 10 years-old son has asthma, and is treated with a steroid inhaler. Will this treatment cause him to be shorter in the future?

A. Lower doses of inhaled steroids were generally found to have a smaller effect on growth.
However, it seems that there is compensation for the growth delay, for example by growing for longer periods, so that the long term effect is apparently minimal.

Q. Any suggestions for coping with asthma in 5 year old? My daughter has asthma. It comes on when she has a cold or an ear or throat infection. I had to give her a liquid steroid last night as she had asthma really badly, the trouble is the steroid makes her so hyper-active, jumping off lounges and running around etc. It drives me crazy because she really needs to rest. I have seen specialists and this is what they all prescribe. What sort of medications do you give your asthmatic child? Are there any new developments I'm not aware of? I would really like some natural remedies if there is any, or diet tips.

A. hi whiteh,i am a retired respiratory therapist,depending on how bad your child is with her attacks will determine what types of meds work for her steroids are given for bad asthma an it might be the only thing that works good for her,her dr knows best.if your child has a regular dr. get a pulmonary specialist for her.----also steroids should NOT BE STOPPED right AWAY if your child has been on high doses this can cause her to have a bad attack.---mrfoot56

Q. How long steroids takes for me to build my muscles? I am very much eager to go for muscle building. I feel that if I take steroids then it is a better option to build good muscle cuts. But as I know that it has bad impact on general health so I do not want to keep that option as such now. But I want to how long it takes for me to build my muscles?

A. brandon is right,even in pulmonary medicine,steroids are used as a last try,in breaking a asthmatic attack,,,,the one thing i know it does,in simple terms,is take all the calcium out of your bones......mrfoot56
